If you would like to solve the equation 7 * x = 42, you can calculate this using the following step:
7 * x = 42 /7
x = 42 / 7
x = 6
The correct result would be A. x = 6.
The answer is A
We have. x=1, then we substitute that on x+z = 20, to solve for z.
1+z=20
z=20-1
z=19
Then we substitute both values x=1 and z=19 on the other equation.
2x +2y+ z = -12
2*1 + 2y + 19= -12
2y= -12 -19-2
2y= -33
y=-33/2
It is positive!
I hope you have a good rest of your day/night :)
Answer:
Step-by-step explanation:
cos(x) = 179/202
x = arccos(0.886138613861)
x = 27.608033...
x = 28°
Okay, so we know that on Friday there were 120 cars in the parking lot out of 200.
That's 120/200.
We need to simplify that to make the denominator 100 so we'll divide both the numerator and denominator by 2.
This leaves us with 60/100
Which converts into 60%
Hope this helps!
